Most Popular homeland: question jason7k7 : What are some of the demands of our land electrically conducting science experiment We are an encounter, why the soil conducts electricity. Our strategy is to provide a 9V battery in three cm soil depth and spot the needle on the meter above the ground and see how considerably tension is there. Mud has given us the .two V voltage from the 9V battery and dry soil was the least (.03 V). We want to know some applications, it will be valuable, and the
